pipe 17 just back of the nozzle as in the case p of pipe 8. The branch tuhhlnr frame 12 s srzncwhat longer than the corresponding above may be used separate tor employment of two gases such as oxygen and hydrogen gases, air and hydrocarbon or other gas, or

and at the same tiinc, permit the gases to flow around the edges or the diaphragms 41 j and between twin and the inner .walls of the body 11. 'lhis mixer and pressure rcduccr may be of any other suitable construcuon it so desired or may be omitted altogether. When used in conj unction with the nuxer 37 in the pipe 8 near the nozzle 9 it acts to mix the gases iron: the nipples 5 and 6 to a greater or less extent and the completing or the nuxing operation is performed by the mixer 37 nmnediatcly berore the gases are burned at the nozzle.

'1he blow pipe which 1 have described acetylene gas and air. The nozzle pipe 8 and nozzle may be changed by using in place of that shown either one of the pipes and nozzles S, 20 or 17 shown in Fig; 15 or any other suitably shaped nozzle pipe to suit the character or work to be pcrlormcd. The nozzle and its pipe may thus be,interchangeable and this 15 the simplest example of the interchangeableness or the blow pipe in the more extended structure of my in-' vcntion, I provide a second set of parts corresponding in all material particulars to those above described except. that they are prel'crubly somewhat lengthened and the nozzle tune extends'so that. the nozzle thereof may come above and close to the nozzle 9. ltelerring to this addition, 12 is a. branch tubular n'ame having valved nozzles 15 corresponding to nipples 5 and 6 of branch tubular irame 2. the discharge end of the branch tubular frame 12 connects with the tube 16 having at its top the mixer and pressure reducer 11 and the union 10. The nozzlc tube 17 is secured to the union l0 and is bent over and its free end fitted with the nozzle 18 corresponding to nozzle 9 and in: iucdiately' in lateral ahnement with it. A mixing device 37 may be employed in the bran h frame 2 and is adjustable in hearings lat oi yoke 3 and bcarin 14 of yoke 4, which. yokes are rigidly secured to the branch frame 2. Secured to the tube 7 are the yokes 25 and 26 and these also connect with and guide the tube 16 from the branch 25 receives thebody 210i 9. chuck which is clamped to the yolie by nut 28' and our-.- rounds the pipe 16. A clamping nut-3t) scxews down upon the split tapered jaw 29 of the chuck and. causes the jaw to clamp. t c tubc 16 so as to hold it in any,adjustcd position. By'means of this adjustment the nozzle 18 may be ad'usted to or from the nozzle Q's-s indicate in Figs, 2, 31nd 4.

It is evident that any other manner of adusting and clamping the parts in adjusted position muybe employed in lieu of that shown. This additional nozzle 18 and its appendages may be employed to project the same gases as the nozzle 9 or dill'crent gases as may be desired, whereby it may be used I to increase the size of the flame or to intensity it or change its chemical qualities according to the gases employed.

In addition to the combination blow pipes above described, 1 provide in practice a third blow pipe of somewhat modified construction, as follows :-A pipe 21 is arranged between the pipes 7 and 16 and extends upward through elongated slots 35 and 36 respectivcly in the yolres 3 and 4, elongated slot 34 in yoke 25 and elongated slot 33 m yoke 26. The slots 33 and 34 are wider than the pipe and receive the means to guide and clamp the pipe 21 in its adjusted positions. The slot 33 is provided with an adjustable guide 32 which may be adjusted laterally and clamped in position without clamping the tube 21. The slot 34 is provided with a clamping guide or chuck 31 (similar to parts shown in Fig. 5) for guiding and clamping the tube 21, and said chuck is adjustable laterally in the slot. The bottom of the pipe 21 is connected with means for supplying it with a gas and, as shown, said means is a branch 22 having nipples 23 and 9A for supplying two gases. 'L'he up .1 end of the pipe 21 is rovided'with t e mixing and pressure re ucing device ll'and the union l0, and secured to the union is the curved nozzle pipe 20 carrying the nozzle 19 and arranged close to the nozzles 9 and 18. This pipe 20 may also have amixing bushing37 zle 19 may he broughtto the positions shown in Figs. 3 anti 4 and again clamped fixedly in position; It will be understood that while, the nozzle 19 has capacity forboth vertical and lateral adj uslment (Figs; 3 and 4), nozzle 18 has capacity for vertical adjustment alone to assume either of the positions of Figs. 2,3 and 4. It will also be understood that this nozzle 19 is adapted for supplying t e same or dill'erentgases as the nozzles 9 or 18, for if the same gases were emplo ed the adjustment of the nozzle 19 relatively to the nozzles 9 and 18 enables various she; 05- fiames to be produced to suit the character of work to be performe While I have shown the mixing and pressure reducers 11 on each of the three es 7, 16 and 21 they may be omitted from cit or or all of said pipes if so desired; and likewalls i l l 084,514" I v a ada ted forvarious hlvti of work by prm ducmg diilerent kin-11s and shapes, of flames,

i and it. is amost impnrtunt. part of the invention that the nozzles are adjnniable n; to relative positions and also tlmt the nozzle pipes'nre replaceable by others when new;-

szuy to reach the place in the work to he operated upon.- Instead of the nozzles and nozzle. )ipes shown in-l ig. t, i may employ other orms ofpipes, as shown for example in F ig. 1."); In the preferred form of nozzie, I make the body with flattened sides so that they may bendjnsicd rinse up to each other to bring the Jets as szlcse ioguther an possibla'.

It is also seen that the. several )ipes 8, l7 and 20 are each of a ditiereni; ength and bend so as to rencn from diner-exit distances nnd bring the nozzles close together; and it is evident that if-t'no unions were not employed tlitSfi pine? Qonid be BFYHHV-Ii in the order 17, 20 and 8 of? lli'r'tl'iitld in rhevrei-erse order by s mply screwing them in place in suitable con 'rling sleeves or sockets carried at the tops of the pipiw 1%), 2i and 7.

The nozzles 9 and it) and their a pendagcs may be used together or said mm: c 1'.) with its appendages may be employed with nozzle 18 and iis. n niendugczs, r it may be omitted altogether ii so desired.

I have shown my blow pipn structure in its most complete 5 1m and hence while I prefor to construct it as here i nown, I do no in the particulars above einunr-rziied and the details likewise may be :nnditicd w thmit do parting; from the spiri? of the invcntion.
